Wireless Sensor Networks (WSNs) are being increasingly used due to their wide range of applications in military and civilian domains. These networks are prone to security attacks. Some of the inherent features like limited battery and low memory make sensor networks infeasible to use conventional solutions of security, which needs complex calculations and more memory. There are many types of attacks on these networks that can be classified as routing attacks and data traffic attacks. In sensor nodes some of the data attacks are black hole, wormhole and selective forwarding attack.
